Hi guys Im building another Thomas Henry VCO555 and im trying to make it as stable as possible in terms of temperature stabilization. My first VCO555, i soldered both transistors with the flat sides surfaces touching and used heatshrink tube connect them even thighter. On top of the two trannies i’ve put the 2k tempco resistor. I wished the resistor was flat instead of round so the heat from the trannies would transfer better to the tempco. My question is, can i use heat conductive paste to put onto the transistors and put the tempco in it for better heat transfer? Thanks in advance for your advice ---

Yeah​👍 Thats the one. Thanks for sharing. Can you send a drop or two?😁 Also, nice PCB. Here is mine ![20260411_215459](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/3X/4/6/46f3412ac0b55aaad3396d0a74b4cd6b4fda64e2.jpeg)
